TIME SLOT COMMUNICATION SYSTEM Russian patent published in 2019 - IPC H04L7/08 G06K7/10 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to a communication system. Said communication system contains a communication station for communication with a number of radio tags by using a time slot communication method in which a number of time slots are provided per one time slot cycle in a repeating sequence for communication with the radio tags and each time slot is characterized by a unique time slot symbol, the communication station transmits a synchronization data signal to the tags, containing the time slot symbol for the current time slot, the tag switches from a sleep state to an active state at a wake-up time, and to receive the synchronization signal in the active state, to establish synchronism with the communication station by recognizing the time slot symbol which appears at the expected time, and it shows the time slot intended for it, and, if the received symbol of the time slot displays the time slot specified for it, a wake-up time corresponding to the next occurrence of the time slot specified for it is determined, wherein the radio tag, after having received and determined the synchronization signal, re-enters the sleep state and remains there until the next cycle of the time slot at a new wake-up time awakens again and changes the sleep state to the active state.

EFFECT: reduced energy consumption.
